Question

Max completed 12 questions on the exam. This is 40% of the questions. 1. Write an equation representing this situation. 2. How many questions are on the exam? 3. Explain how you got your answer

Answer 1

Explanation:

How many questions are on the exam? Represent this by n.

Then 40% of n comes out to 12 questions, or more symbolically,

0.40n = 12, after which we get n = 12/0.40 = 30

Answers:

(1) 0.40n = 12 is the desired equation.

(2) n = 30 is the number of questions on the exam.

(3) See above for explanations.
